I recently did this to an earring set that I had already photographed and LISTED IN MY SHOP...it's still there, in fact, missing one of its' little balls...my MOM noticed it (I never did until she pointed it out) and I had to unset the stone and resolder the ball. Now I just have to re-take the pics, which I haven't yet. With as many hearts as the item is getting, I bet I sell the earrings as soon as the new pics are up! LOL!
It sucks, but sometimes it's necessary...and you'll get really good at tugging on all of those pieces (with GOOD force) before setting stones! :)
